secondcor521 Do you feel there is a reason she should choose a Roth IRA over a Traditional IRA?
Others have given good responses, but since you asked me I'll give you my thoughts.
I'd say as long as she's saving towards retirement and doing it in a tax-efficient manner, that puts her well ahead of nearly all her peers and she'll do well regardless. So Roth, traditional, SEP, whatever are all good choices.
Over the years of our kids' lives, they'll be in various tax brackets. Broadly speaking, as I see it, if you have to pay taxes, you want to spread them evenly over long periods of time to stay out of the higher brackets.
So there are two basic leveling strategies: defer and accelerate. Deferring means avoiding taxes now, paying them later when you hope to be in a lower bracket. Accelerate means paying taxes now, avoiding paying them later when you guess you'll be in a higher bracket.
I tend to frame this in my mind as there is some income tax rate that I should be happy to pay (because it's lower than what I think I'll be paying in the future), but avoid anything higher (because that would be higher than what I'll be paying in the future).
It takes making guesses about what income taxes will do in the future and what one's income sources will look like in the future. Each person has to do this for themselves, but if you sit down and noodle on it and scratch out a bunch of tax returns, and do some Excel modeling, you can get a good guess.
My guess was that your daughter, if she is already making that kind of income at a young age, will probably be a high earner in the rest of her life. So this year might be a low income year for her. So she'd want to choose the "accelerate" option and pay taxes now. A Roth is post tax, so she'd be paying the taxes on her contribution.
But maybe my guess was wrong.
If you think this high income early is an anomaly, and she'll have some low income years in her future (either college, time off for travel/sabbatical, a low-income career, or FIRE could create those low income years), then she'd want to choose the "defer" option. Contribute to a traditional IRA, avoid the taxes now, then do a Roth conversion in those low income years to pay the taxes then.
That's my thought process.
